Block Casting Numbers
These are the numbers pulled from an engine in an 80 F-150 Explorer with a 302.This is not the original engine....apparently (I know the first second and third owners) the factory engine was a lemon and was replaced with this one.....Here are the numbers...and thanks in advance.
D4DE 6015-AA-0

Correct...I did a litle research...guess I was a little too anxious.....the problem I have now is that the 2nd owner (the original owner's grandson) said the above in the first post...but if that story is true?How is it that the engine has E7TE heads?What year did they start fitting these heads onto engines?Thanks.

It didn't change much at all.....the issue is....if this motor was dropped into the truck in 1980...then how did the E7TE heads find their way on there?As far as I know...the only time this engine has been played with was way back in 1980.....Later

You might want to measure the valves in those e7's to see if they've been modified. Should be 1.78" and 1.46" in stock trim.
Maybe the PO had a junk yard rat who found a cheap set to pocket port for some cheap ponies?? I've seen ported e7's on an '83 mustang that weren't OEM.
Just some ideas...
Mike
p.s. Time to stroke that block JR!

D4DE is the Ford ID number for D4DZ = 1974 Maverick/Comet.
But, just because casting number prefix D4DE refers to a '74 Maverick doesn't mean that's what the block was cast for, in fact...it was cast for all 302's.
Casting numbers cannot be translated to actual Ford part numbers, because one casting number might refer to multiple finished blocks (or heads, manifolds, you name it). Example: D1VE-6015-AB is the casting number used for both 1971/79 429 & 460 engine blocks.
D4DE-6015-AA: The same finished 302 engine block was used from 1974/79, replaced in 1980 wth E0AZ-6010-A, which was used at least thru 1984 for ALL 302's. Replaced: E0AZ-6010-A is now the correct service part for all 1974/84 Ford 302 engines.
E7TE = 1987. The finished heads from this casting number are: E7TZ-6049-C & E7TZ-6049-K. These two heads replaced other Ford heads from 1978 thru 1986 (D8AZ-D; E0AZ-A; E5AZ-A; E5AZ-C)
Ford updates part numbers on a daily basis...keeping track of all these updated part numbers is a major PITA.

Mike, I'd love to stroke her out but it's not mine to do that with...however, my buddy has a 289 ZZ motor that will be a very interesting swap in the future...hopefully the very near future.Numberdummy......the sites I researched from are those posted in the smallblock forums.The casting also extends further than what you have said...I beleive it's 70-79 For the Maverick or Grenada.Digging further into that the casting numbers also came in a 74 Ford Maverick.The Block was also stamped 3J4 which means what? 3= the year so, 1973 J=month which means what semptember or october, and the 4 indicates the date which would be the 4th.I have checked the heads 3 times and I believe they say E7TE but I will check them once again when I get a chance just to be sure.Thank you for all the information and for the straightforward reply Paul.Later all

Prior to 1974, the service part number bare block was: D1TZ-6010-B. The casting number for this block could have been D0 or D1. The D1TZ block replaced: C9TZ-C. C9TZ-C replaced C8TZ-B. C8TZ-B replaced the original 1968 302 block: C8ZZ-6010-A.
I say again, the 3rd digit could be D for Maverick, or T for truck, or Z for Mustang..but casting numbers do not translate to actual part numbers and all these blocks were used in everything Ford offered the 302 engine in: Ford; Fairlane; Torino; Mustang; Maverick; F100 (69/72) yadda yadda yadda.
The 302 HiPo used a different block.
Maverick = 1970/77 Introduced midyear 1969. No Maverick or Comet offered a 302 V8 till 1971.
Granada = 1975/82.
302 engine introduced spring 1968.

This same finished block also was used as a service part replacement (service part = sold by Ford dealers) back to 1968!
So any range of years from 1968 thru 1973 could have had that D4 casting number, either installed as a new service part replacement bare block, or by way of rebuilt engines...BUT NOT WHEN THE VEHICLES WERE NEW! Es Imposible!

Yup, only GM encodes their blocks with an ID number to indicate what car it was originally installed in. Ford castings are used across the range of vehicles regardless of what car code was used in the casting number.

No, I DO get it.....I'm not a wiz when it comes to history of stamped codes and I sure as hell don't claim to be......a person is only intelligent as his sources so I'll excuse your reaction.Thank you for the information.
